d20 Mecha
GoO's book "d20 Mecha" has been pushed back to an "early August" release. While preparing the book, they worked with another company called "Dream Pod 9", who was interested in converting all of their mecha into d20. DP9 used the mecha creation system devised by GoO, and wrote a book called "d20 Mecha Compendium". Originally, the two books were to be released at about the same time, but when GoO kept postponing the release of d20 Mecha, DP9 decided to proceed with the release of the d20 Mecha Compendium.
In essence, we have the sourcebook (the compendium) out months before the core book (d20 mecha).
